4.1.6 Use a special solar cable and plugs for installing the PV system and make sure that all
connections are safe and tight. The cable cross section size should be 4mm
2
(12AWG) and able to
withstand the maximum possible system open-circuit voltage.
4.1.7 Bypass diodes are included in module junction boxes to avoid decreased module performance
in the event of shade or shelter. Please check the relevant product datasheet for the specific diodes of
J-box.
4.1.8 It is recommended to install anti-reflection diode in the header box or group series inverter.
4.1.9 The maximum number of modules that can be connected in series must be calculated according
to the relevant regulations. The value of the open-circuit voltage in the local minimum temperature
condition cannot exceed the maximum system voltage of the module (the maximum system voltage of
the module is DC1000V/1500V according to the IEC61730 safety test) and the value required by
other DC electrical module.
It is recommended to calculate according to the following formula:

4.1.11 The minimum bended radius is 43mm and prohibit to excessively bend. After the
assembly is installed, the cable shall be fixed in time, and the cable shal l not swing back and
forth for a long time.
